Step‑by‑Step Instructions for Cozy Creamy Spinach Mushroom Lasagna
Step 1: Prepare the Béchamel
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Once melted, whisk in ¼ cup of flour to form a roux and cook for about 1-2 minutes until lightly golden. Gradually pour in 2 cups of milk while whisking continuously to avoid lumps. Continue stirring until the sauce thickens, around 5-7 minutes. Remove from heat and stir in a pinch of nutmeg. Set aside the béchamel sauce.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add 3 cloves of minced garlic and sauté until fragrant, about 30 seconds. Then, toss in 8 ounces of sliced mushrooms and cook until they turn golden brown, roughly 5-6 minutes. Finally, stir in 4 cups of fresh spinach, cooking just until wilted, approximately 2 minutes. Remove the skillet from heat and set it aside.
Step 3: Layer the Lasagna
Preheat your oven to 375°F (190°C). In a 9×13 inch baking dish, spread a thin layer of the béchamel sauce across the bottom. Layer 3-4 lasagna noodles over the sauce, followed by half of the sautéed mushroom and spinach mixture. Sprinkle 1 cup of shredded mozzarella cheese on top. Repeat these layers, finishing with noodles, béchamel, and ½ cup of mozzarella on the top for that delicious golden finish.
Step 4: Bake the Lasagna
Cover the baking dish with aluminum foil to prevent sticking. Bake in the preheated oven for 30 minutes, then carefully remove the foil and bake for an additional 15 minutes. The lasagna should be bubbling and golden on top when done. Trust your senses; the enticing aroma will guide you to the perfect moment!
Step 5: Rest & Serve
Once baked, remove the lasagna from the oven and let it cool for about 10 minutes before slicing. This resting period helps the layers set, making for cleaner cuts. Garnish with fresh herbs if desired, and serve warm. Enjoy your cozy creamy spinach mushroom lasagna—perfect for heartwarming dinners!

Expert Tips for Cozy Creamy Spinach Mushroom Lasagna
- Thickness Matters: Ensure your béchamel sauce is thick enough to support the layers. If it’s too thin, whisk in additional flour while cooking.

Yes, you can! If you’re looking for a dairy-free version, consider using almond or oat milk instead of regular milk.
